HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 731,529, dated June 23,1903. Application filed February 24, 1903. Serial N0.144,858. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, EVERETT H. WHITE, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inHose-Nozzles; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to hose-nozzles, and has for its object to improveupon the con struetion shown and described in Letters Patent No.599,967, issued March 1, 1898, to Albert D. Laws.

The principal end aimed at by my invention is to provide a hose-nozzleof the type shown in said patent in which the interior spindle shallhave no permanent integral projections such'as would interfere with theready application or removal of the packing and packing-retaining ring,while at the same time provision is made so that the spindle .cannot bewithdrawn from the body of the hose-nozzle unless the stufling-box befirst removed.

With these ends in View my invention consists in certain details ofconstruction and combination of parts, such as will be hereinafter fullyset forth and then specifically be designated by the claims.

In the accompanying drawings, which form a part of this application,Figure l is a side elevation of my improved nozzle; Fig. 2, a sectionalelevation of the same with the parts assembled in condition for use;Fig. 3, a detail interior view of the stuffing-box with the packing-ringcontained therein, and Fig. 4 a section at the line w w of Fig. 2. i

Similar numbers of reference denote like parts in the several figures ofthe drawings.

In the patented construction above referred to the rear extremity of thespindle is cylindrical and of uniform diameter up to the point where itadjoins the coupling-box which attaches to the hose, and at the forwardend of this cylindrical portion is a cone shoulder,

and a ring of packing material flanked by lindrical portion.

split metal packing-rings must be forced over this cone shoulder beforesaid rings can assume their proper position upon said cylindricalportion. It will be readily understood that a ring of packing material,especially if formed of the usual wicking or other similar clingingsubstance, must be more or less mutilated and distorted by the act offorcing the same over this cone shoulder, and, moreover, these rings arenot readily removed from the spindle, since the metal rings have to besprung over the same with some sort of a tool, while the ring of packingmaterial must be torn from the cylindrical portion in bits or else cutaway bodily. My invention aims to obviate these disadvantages and willbe best understood from the following description.

1 is the nozzle-body, having the flaring mouth 2 and contractednozzle-opening 3, said body being interiorly threaded at or about itscentral portion, as seen at 4, and exteriorly threaded at its rear end,as seen at 5, all as shown and described in said patent.

6 is the hollow cone-spindle, having on its forward extremity the usualdouble cone 7 and provided with openings 8 (only one shown) near itsforward end, while the rear end of said spindle terminates in aninteriorly-threaded box 9 for attachment to a hose, all as and for thepurpose set forth in said Letters Patent. At or about its middle portionthe cone-spindle is exteriorly-threaded, as seen at 10, which threadengages with the interior thread of the nozzle-body, While at the rearof this threaded portion 10 the spindle presents a plain cylindricalbody of a uniform diameter. In fact, the entire spindle between the box9 and the openings 8 is cylindrical and of uniform diameter, since theapices of the threads are substantially flush with the circumference ofthe plain cy- Near its forward end this plain cylindrical portion ispierced diametrically from one side to the other,'so as to contain asmall pin 11, which is dropped loosely through these holes thus pierced,the length said pin being such that its ends will project beyond thecylindrical portion.

12 is the stuffing-box, whose forward end is threaded interiorly and isadapted to engage with the thread on the rear of the body portion 1, therear end of this box being contracted to form a shoulder 13. 14 is thepacking, which is confined within this stuffing-box between the shoulder13 and a ring 15, which is driven into said box against the packing.

Presupposing the parts to be secured together in the manner shown atFig.2, they are readily detached by first unscrewing the stuffing-boxfrom the body of the nozzle and then slightly retracting the spindle, soas to allow the pin 11 to drop out therefrom. The spindle may then bereadily withdrawn from the body 1 and from the stuffing-box without inthe slightest degree disturbing the packing or the ring 15.

When it is desired to put the parts together, the spindleis merelythrust through the stuffing-box, the pin inserted in place, and thespindle then properly assembled With respect to the body portion.

The advantages of my improvement will still further be appreciated whenthe fact is recognized that the stuffing-boxes may be fully equippedwith the packing material and the packing-ring, so as to reallyconstitute but a single element in the assembling of the parts of myimprovement.

It will be observed that the tightening of the stufling-box of courseeffects the proper compression of the packing and that there can be nodanger-of leakage.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is p 1. In a hose-nozzle, the combination ofthe body and spindle adapted to engage by means of suitable threadedportions, said spindle being cylindrical and of uniform diameter at itsrear end, the stuffing-box secured to the rear end of said body bysuitable threaded portions and containing suitable packing and disposedaround said cylindrical portion of the spindle, and the pin looselyextending diametrically through said cylindrical portion and projectingtherefrom, substantially as set forth.

2. In a hose-nozzle, the combination of the nozzle-body interiorlythreaded at or about its central portion and exteriorly threaded at itsrear end, the hollow spindle exteriorly threaded at or about its middleportion and terminating at its rear end in an interiorlythreadedconnecting-box, said spindle immediately beyond said box beingcylindrical and of uniform diameter and having throughout its length nopermanent projection which extends beyond said cylindrical portion, thestuffing-box interiorly threaded at its forward end and adapted toengage the rear end of the nozzle-body while the rear of saidstufiing-box is contracted into an annular shoulder, the ring withinsaid stuffing-box, the packing confined between said ring and shoulder,and the pin extending diametrically and loosely through said cylindricalportion of the spindle and projecting beyond the surface thereof,substantially as set forth.

3. In a nozzle, the combination with a hollow body portion, of a spindlethreaded into the same, a packing-ring removably carried by said bodyportion and surrounding said spindle, and a loosely-mounted removableabutment carried by said spindle for limiting the longitudinal movementof the same, substantially as described.

4. In a nozzle, the combination with a hollow body portion, of a spindlethreaded into thesame, a packing-ring removably carried by said bodyportion and surrounding said spindle, and a removable abutment carriedby the spindle and revoluble therewith within said body portion,substantially as described.

- 5. In a nozzle, the combination with a hollow body portion, of aspindle threaded into the same, a packing-ring removably carried by thebody portion and surrounding said spindle, and a pin removably extendingthrough said spindle and movable therewith within the body portion,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EVERETT I-I. WHITE.
